The Prophet (salAllahu alayhi wasalam) said, ‘Whoever recited Surah al Kahf in the same manner in which it was revealed, it will serve for him as a light on the Day of Judgement, from his domicile to Makkah. And whoever recited the last ten verses, and it happens that the Dajjal should appear after that, Dajjal will not be empowered over him’. [Hakim 1/564 & Dhahabi]

Abu’d-Darda’ reported that the Messenger of Allah (salAllahu alayhi wasalam) said, “Anyone who memorises ten ayats from the beginning of Surat al-Kahf (18) will be protected from the Dajjal.” [Muslim, Riyad as-Salihin by Imam an-Nawawi 183 #1012] One variant has, “from the end of Surat al-Kahf.”

The Prophet (salAllahu alayhi wasalam) said, ‘Whoever recited Surah al Kahf on a Friday, Allah will kindle for him abundant light to brightly illuminate the period between the two Fridays (the Friday on which the recitation was made and the next Friday)’ [Hakim 2/367, Mishkat al-Masabih #2175, however Baihaqi disagreed with it’s authenticity in Sahih Al Jami 2/1104]

Narrated Al-Bara’bin Azib: A man was reciting Surah Al-Kahf and his horse was tied with two ropes beside him. A cloud came down and spread over that man, and it kept on coming closer and closer to him till his horse started jumping (as if afraid of something). When it was morning, the man came to the Prophet, and told him of that experience. The Prophet said, “That was As-Sakina (tranquility) which descended because of (the recitation of) the Qur’an.”
[Sahih al-Bukhari 6:61 #531, at-Tirmidhi 2810/A]

The hadith that you have mentioned above for sura kahf resembles as the one mentioned in Tafsir Ibn Kathir, The virtues of Surah Al Baqarah.

Al-Bukhari recorded that Usayd bin Hudayr said that he was once reciting Surat Al-Baqarah while his horse was tied next to him. The horse started to make some noise. When Usayd stopped reciting, the horse stopped moving about. When he resumed reading, the horse started moving about again. When he stopped reciting, the horse stopped moving, and when he resumed reading, the horse started to move again. Meanwhile, his son Yahya was close to the horse, and he feared that the horse might step on him. When he moved his son back, he looked up to the sky and saw a cloud radiating with light that looked like lamps. In the morning, he went to the Prophet and told him what had happened and then said, “O Messenger of Allah! My son Yahya was close to the horse and I feared that she might step on him. When I attended to him and raised my head to the sky, I saw a cloud with lights like lamps. So I went, but I couldn’t see it.” The Prophet said, “Do you know what that was” He said, “No.” The Prophet said,

(They were the angels, they came close hearing your voice (reciting Surat Al-Baqarah), and if you had kept reading, the people would have been able to see the angels when the morning came, and the angels would not be hidden from their eyes.)

This is the narration reported by Imam Abu Ubayd Al-Qasim bin Salam in his book Fada’il Al-Qur’an.
